DOOR-LOCKING APIPARATUS.

Specification of Letters Patent.

Application filed. September 21, 1918. Serial No. 255,105.

- To all whom it may concern:

Be it known that I, ALBERT PETER, a citizen of the United States,residing at Kingston, in the county of Tuscola and State of Michigan,have invented certain new and useful Improvements in Door-LockingApparatus, of which the following is a specificaillustrated in theaccompanying drawings,

specifically described in the following specification and moreparticularly pointed out in the appended claims.

In the drawings,

Figure 1 is a view in front elevation of a cabinet or structure equippedwith my looking apparatus, while i Fig. 2 is a vertical, sectional'viewtaken on line 22 of Fig. 1.

Fig. 3 is a horizontal, sectional view taken on line 33 of Fig. 2.

Fig. 4 is a fragmentary, perspective view of the apparatus.

Fig. 5 is an enlarged, vertical sectional View of the apparatus.

Fig. 6 is a view in side elevation of the manipulating handle or controland the cooperating parts associated therewith, the parts shown in thisfigure being removed from the frame or cabinet.

Referring to the drawings by numerals, 1 designates the cabinet or framewhich is provided with preferably a plurality of pairs of hinged doors2, 2; each door is provided with the usual knob or grip 3.

Secured across the cabinet 1, and extending across the inner face ofeach door 2, is a supporting bracket or cleat 4; this bracket 1, in eachinstance, is preferably placed near the upper end of the upper doors andnear the lower ends of the lowerdoors, although there is no particularnovelty in the location of the brackets 4, whether near the upper or thelower edges of the doors; the object is to place these brackets 4 out ofthe way so that when the doors 2 are open the brackets will notinterfere with the storing of articles or goods in the compartment orSpaces behind the door or doors.

Arranged transversely of the brackets 4 are auxiliary brackets 5 (Fig.3); and in these brackets 5 are rotatably mounted shafts '6, preferablysquare in cross section, and to these shafts are connected substantiallyU- shaped hook devices 7. Each hook device 7 comprises a body, ofsubstantially U-shape, as stated, terminating at its ends in eyes 8,which surround shaft 6. The hook device 7 is fixedly secured to theshaft by reason of the bore of each eye being square and fitting snuglyover the shaft 6 so that when a rotary movement is imparted to shaft 6,the hook devices 7 will be moved for either looking or,

unlocking the doors 2, as hereinafter described.

On each door 2 is a catch 9, of any ordinary type, which will ride overthe hook device 7, and when the devices 7 are raised,

as shown in Fig. 5, the hooks 9 will securely retain the doors in aclosed, locked position, but when the square shafts 6 are rotated so asto swing the hook devices 7 Fatented Dec. 1'7, 1918.

downwardly, as shown in dotted lines in Fig.-'-

. 5, the catches 9 will be released, and by the operator grasping theknobs 3, the doors can be opened.

' A central strip 10 carries a rotatably mounted disk 11, and to thisdisk 11 is secured a grip or angle plate 12, and pivotally mounted at13, upon the disk 11, are the inner ends of links 14, the outer ends ofthe links being pivotally connected at 15, to arms 16, that have eyes 17formed upon their outer ends, which eyes 17 have square bores that fitsnugly over the square shafts 6, Fig, 6. When the grip 12 is closedagainst the strip 10, Fig. 2, the hook devices 7 will be in a raisedposition, Fig. 5, and as each door is closed the catch 9, carriedthereby, will ride over the hook device and will secure the door closeduntil the operator swings the grip 12 upwardly to the position shown bydotted lines in Fig. 5, whereupon the catches 9 will be released, byreason of the hook devices being then in their lowest position, shown bydotted lines.

The grip 12 is provided with an elongated aperture 18, that permits thestaple 19 to ratus whereby a number of doors ,or gates can be locked bya single operator, and such is desirable in storehouses, or inrefrigerator plants, or by covering the catches so that a criminalcannot tamperwith the same my device may be readily adaptable to aprison or jail.

What I claim is:

1, In an apparatus of the class described,

the combination with a frame provided with a bracket, a door carried bysaid-frame, of a dlsk rotatably mountedupon said frame, a

- grip attached to said disk, a shaft rotatably -mounted upon saidbracket, a hook device carried by said shaft, a catch carried by-sa iddoor andco'operating with said hook device for locking the door in aclosed position upon saidframe, and means pivotally connecting saidshaft to said disk whereby 'movementimparted to the disk through thegrip will placethe hook device in a locked or unlocked position withrespect to said catch.

2 In an apparatus of the class described,

the combination of aframe provided with a plurality of sets of-doors,brackets secured transversely across said frame and being positionedcontiguous to the ends of the T doors sald frame rovlded at its center\vlth a rotatable 'disk,an angle grip provided with an elongatedaperture secured to said disk,

auxiliary brackets secured upon said firstinentioned-brackets, shaftssquare in cross section, journaled in said auxiliary brackets,

hook devices provided with eyes,said eyes having-square bores: andfitting over said shafts,- catches on said doors adapted toengage saidhook devices for retaining the doors in a closed position',ar1nsprovided at their outer ends with eyes fitting over the square shafts,and links pivotally connected at their outer ends to said arms andpivotally connected at their inner ends to said disk.

3. In an apparatus of the class described,

i the combination with a frame, a doorcaral-ly connected at itsopposite'end to said arm.

4. In an apparatus of the class described, the combination with a frame,of a plurality of pairs of doors upon said frame in the same horizontalplane, a single shaft carried by said frame contiguous to all of saiddoors, a pair of U-shaped hook devices fixedly secured to said shaftbehind the doors, said U-shaped hook devices extending from said shafttoward said doors, a pair of catches secured to each pair of doors andeach pair of catches engaging a single hook device, and amanually-controlled operating device secured upon the middle of saidframe, between the pairs of doors, and being connected to the shaft formoving the shaft 1 to'locked or unlocked positions.

In testimony whereof I hereunto affix my signature.
